When I ran vwb it didn't drop at all in 4000 miles. So what gives?
My 2014 Ford Focus used oil for the first 17,000 miles, and early on it was about as bad as yours sounds. It stopped using oil when I stopped using MC 5w-20 semi-synthetic and went to 5w-30 whatever brand. Not a drop went missing from there to 36k when I traded it.
Had the same issue with 2011 Ford Fiesta, only it didn't last as long, car used oil for about 10k, MC 5w-20, swapped it to Supertech 5w-20 and it was worse, finally threw whatever 5w-30 I had laying around at it and oil usage stopped. Nary a clue as to why on either car. No drips or drabs anywhere that I could ever see.
